Comment 2 Anton Gubarkov 2016-08-06 20:02:34 UTC 
I double-tested it with a simple project with only 1 color clip in the timeline - it still crashes.
Comment 3 farid 2016-08-10 15:02:00 UTC 
Which version of MLT do you have installed? (It should be 6.2 atleast)

Do you have Movit (GPU effect processing) turned on?
Comment 4 Anton Gubarkov 2016-08-12 17:42:06 UTC 
I use latest MLT (from git). I do have movit enabled. The error occured due to outdated kde framework (not sure wich part of it). I rebuilt the kde-framework and the error no longer occurs.
I close as INVALID
